I have three UPSes:

1. Clary OnGuard 3 phase 5 kVa UPS, no batteries
2. Clary OnGuard 1 phase 5 kVa UPS, no batteries
3. Ferrups 3.0 kVa inline model UPS (no outlets), no batteries

All are working.

I would like to demolish these UPSes, take out what I can sell and
auction these parts on ebay. I recently demolished an even bigger

Data

General UPS (about 8 kW) and sold the capacitors from it for $75. The
rest is a big pile of unidentifiable parts. Some look like huge

diodes

and transistors. I am afraid that some of those parts have value that
I would have hard times capturing (maybe I took apart a large and
usable rectifier, for example), so, I do not want to make the same
mistake again.

I would like to know which parts of those UPSes are really desirable.

Capacitors?

Rectifiers?

Anything else?

Any thoughts on this will be appreciated. I will use this as an
opportunity to learn about electronics.

Thanks!

Do you ever find 12v dc power supplies through those government
auctions? I am looking for about a 20 amp one.

I can't even give these away.
Especially the old heavy linear ones.

How many dozen do you want?
